Alternatively the sacrificial anode may be composed of zinc or an alloy thereof. The backfill material further includes soda ash, trisodium phosphate or other high alkaline chemicals to raise the pH. The backfill material also preferably includes a moisture retention material such as zeolite to maintain a minimum of moisture content of 10 percent or greater. | 08-20-2009 |

The method permits changing the anode while preventing or minimizing water from exiting the cooling system of the marine engine. | 03-13-2014 |
| 20140251792 | METHOD AND APPARATUS FOR CONTROLLING STEEL CORROSION UNDER THERMAL INSULATION (CUI) - Galvanic anodes and barrier corrosion control for metal pipelines, tanks, and equipment under thermal insulation includes the use of pure aluminum and aluminum alloys in fresh water at high temperatures to protect steel elements in hot water without sufficient chlorides. Sacrificial aluminum and sacrificial zinc-aluminum powders in a mixed primer provide long-term, effective corrosion control of steel under thermal insulation can be achieved in all water temperature ranges regardless of the presence of sufficient chlorides. At temperatures below 75° C., the zinc particles in the primer act to protect the substrate steel. At temperatures above 75° C., the aluminum particles in the primer, and galvanic aluminum tape protect the substrate steel in chloride free neutral pH water and also reduce the consumption of zinc particles in the primer. When the electrolyte water for CUI is sufficiently contaminated with chlorides, the aluminum particles in the primer and the galvanic aluminum become active. | 09-11-2014 |

| 20140251793 | CATHODIC PROTECTION CURRENT DISTRIBUTION METHOD AND APPARATUS FOR CORROSION CONTROL OF REINFORCING STEEL IN CONCRETE STRUCTURES - Mixed-metal-oxide (MMO) coated precious-metal tape is installed directly on concrete surfaces using an electrically non-conductive adhesive with semi-conductive coating or overlay, thereby obviating the need for slots or holes to the concrete structures which are not subject to direct moisture. The tape anodes may be installed on the concrete surfaces exposing metals without developing an electrical short circuit between the anode and the metals due to the non-conductive adhesive. The semi-conductive layer over the metal tape can distribute the CP current uniformly to the entire concrete surface without developing electrical short circuit. Overall the invention provides for quick and low cost installation on many concrete structures. Interconnections between the tape anodes and bare metal distribution elements may be made with conductive adhesive or spot welding. | 09-11-2014 |
